1) Description of Rack
Gear Racks are machine parts which, in combination with a respective gear wheel, convert the rotary
motion into a linear feed and transfer mechanical energy from the shaft to the moving parts or vice versa.
2) Applications of Rack
Rack and pinion combinations are often used as part of a simple linear actuator, where the rotation of
a shaft powered by hand or by a motor is converted to linear motion.
